CS-DMRC6-03-D | Carli Suspension 6 Inch Lift Multi Rate Coil Springs For Dodge Ram 2500/3500 4WD | 2003-2013 | Diesel

In our multi-rate springs, each coil is spaced differently making them a variable spring rate. Initially, it is easy to compress these springs for the first couple of inches. As you apply more force, the coils come closer to each other. After a certain point, the coils at the bottom 1/4 of these springs begin to touch each other and finally become inactive or dead, which makes the spring stiffer.

The more force you apply to our multi-rate spring the more the rate increases. So, these springs are compliant to very small bumps on the road, while achieving control when needed off-road, hard braking, and turning. These springs allow you to achieve the highest performance while driving hard and providing a smooth, comfortable drive the rest of the time. For 2010 trucks, we have found that using a Linear rate coil works best with the heavier 4th Generation vehicles, giving a very supple and smooth ride while still keeping performance to the absolute maximum.
